[0002] The sidewalk refers to the part of the road that is separated by curbs, guardrails and other similar facilities and is intended for pedestrians, while the shoulder refers to the strip of a certain width (including hard shoulders and earth shoulders) located from the outer edge of the carriageway to the edge of the roadbed. It is used to maintain the function of the carriageway and for temporary parking, and serves as a lateral support for the road surface.
[0003] The existing shoulder stones on the sidewalk are in use. When the road surface is renovated, it is often necessary to remove the shoulder stones. The conventional removal method is for two workers to hold the clamping rod and let two clamping blocks clamp the shoulder stones and then remove them. However, the clamping blocks are usually fixed, and the width of many shoulder stones is narrow, resulting in the inability of the existing clamping blocks to clamp the shoulder stones, and the adaptability is poor.
